Networking hardware includes the physical devices facilitating the use of a computer network. Typically, networking hardware includes gateways, routers, network bridges, modems, wireless access points, networking cables, line drivers, switches, hubs, and repeaters. But it also includes hybrid network devices such as multilayer switches, protocol converters, bridge routers, proxy servers, firewalls, network address translators, multiplexers, network interface controllers, wireless network interface controllers, ISDN terminal adapters and other related hardware.

If you have a brand new chassis, what's needed to be done to make it functional?  Do you have to 'turn on' SUP?  How about installing line cards- is it plug and play, or do you have to 'turn on' the cards?  Is it like nexus chassis where you have to enable features?  Is there an order of operations when installing a new chassis?

What's the proper way to install a switch stack, and troubleshooting?  (Method of power, choosing master, IOS matches)

Scenario 1:
Existing 3650 already there, and you want to add an additional switch to it as a member/slave.  


Scenario 2:
Installing two brand new switches into as a stack.

Scenario 3:
How to solve mismatch software versions?  What's commands to use?  

Scenario 4:
Existing 3650, and you want to add an additional 3650 to as stack, but want to make new switch master?  What's the proper way to do this?  

Scenario 5:
installing 3750X. Are there any differences from 3650's listed above now that StackPower is involved?

What are the differences between IOS, IOS-XE, IOS-XR?  Examples of syntax differences if any like NX-OS vs IOS?  If I see 12.X is that IOS and 3.X is IOS-XE?

Hi, after spending 30 mins configuring my cisco 2690 switch through the console I now have access to the switches GUI.... I prefer to configure through this due to simplicity.

The problem is that the GUI does not support any modern browsers. I cannot click any links when logged in and it warns my browser is not supported....

How do I fix this?

What's defined as a hot-cut?  
-Using existing rack/cables?
-Do outages go hand in hand with hot-cuts?  Or are outages/blackouts defined as operations 'ignoring' the flags that occurring, or is it an actual 'outage'.  

What is swinging? (L3 swing, swing over L3, etc.)
-Is this 'swinging' IP schemas?  Original is 10.0.1.0/24, new devices will be 10.0.2.0/24.  Maybe the schema is the same?  It could mean a lot of things as well, but elaborate!

If ISP is on the call with us, what are some validation commands I should ask for (QoS, MPLS, basic connectivity)?  Please list!

show ip interface brief....etc.

How can you tell whether you have MM or SM fiber by looking at it?  Micro?  62.5 vs 50 = multi vs single?  I'm guessing color isn't relevant.  The current setup I'm looking at says LX for the SFP module on the switch, but the technician out there is saying its MM fiber...is there such a thing as SFP that runs both SM/MM?  Link please.  This is on a 3750G, it uses the old X2 interface where a TwinGig module is installed at the uplink with SFP's connected.  The SFP's say LX, and there isn't a model description about the SFP from 'show inventory'

Guys,

I have a mac that is running in a network behind a sonicwall tz205. The mac is not being filtered at all in fact i have its mac address to be exempted from all filtering. However, both the wifi and the ethernet are very slow. All other computers on the network are reporting are 20-25 mbs down and 15-20 mbs up when running speed tests. This particular mac is reporting somewhere around 5-6 mbs down and 2-4 mbs up. This is on an internet circuit with 75 down and 25 up bandwidth. Also, this mac is running El Capitan.

I am troubleshooting a server to clients connectivity issue. I have changed all patch cords and swapped the rj45 jacks. I have not tried installing a new NIC in the server as of yet. However, I did discover today that the cat5 cables at the 12 port patch panel only have the orange and green pairs punched down as per 100 base tx. I wonder if anyone has run into any intermittent connectivity issues when running Gig E on only 2 pair 100 base tx.

Hi Experts,
I have an issue with a fax line and can't figure out where the issue is coming from.
I have a phone line (no DSL) connected directly into a fax machine. when dialing the number the fax machine picks up but no handshake is happening ( the weird noise that we are supposed to hear from a fax)

I thought the fax machine was bad , so I brought another fax machine that works and plugged it in the same line and I am getting the same issue. How can I troubleshoot the issue of this line?

here is what is new and I am sure the issue is somewhere there. I ran multiple network cables for a new location of the fax ( I used a network cable , and I have done it numerous time at different locations) , I tested the cables with my tools and they work fine. so unless the cable(cat6) has some rating  that is not compatible with the fax line I am very clueless on how to test this issue.
What is weird is that it rings, the fax pickup but no sounds of the fax signaling.

Any help would be appreciate.
Thanks

I have a remote site connected via a VPN tunnel. At the remote site there is an HP LaserJet M4555 MFP. I am able to connect workstations located in the remote office to the MFP, I am able to ping the MFP from my home office via the VPN tunnel, I am able to access the MFPs Admin GUI from the home office via the VPN tunnel. I can connect my workstation to the MFP via web services (not TCP/IP) and successfully print a test page. Attempts to connect to the printer via TCP/IP from the home office fail. Attempts to add the MFP to my print server located in the home office fail.

What could be causing the inability for me to connect to the remote MFP when all network communication appears to be functioning?

Hi, I would like to connect my SAN, Backup and VM Servers together at 10gb/s. They all have 10gb NICS in them.

Could you recommend me a good Cisco 10GB Switch. I only need 8 - 16 ports on it.... 24 if I have too but I am not sure which switch to go for...

Thanks.

I want unlimited GIG on my windows 7 laptop for one month

I am using a prepaid phone so do not suggest using phone
phone is another question

my isp is only for my residence and is not portable, so suggesting my isp is not an option for this question but maybe a future question

i have one computer so I do not want to buy an expensive hotspot for many computers

Is there something like the clear wireless usb stick with unlimited internet on a $50 device for $50 a  month no contract

Clear wireless was bought by sprint

Situation: I have residential internet from Time Warner Cable. The coax cable comes in the living room, and is split. One end going into my Netgear router, and the other end going into the DVR. The router is a modem and wifi router (2 in 1).

Problem: The wifi does not reach my bedroom, and for gaming, I need a wired connection. Running a cable from the living room is not an option.

Idea: I came up with an idea, after realizing that the TV in the bedroom is connected to the same coax cable that's in the living room. So I thought, can I replicate in the bedroom the same setup as in the living room? In other words, purchase a 2nd Netgear router, and take the coax cable feeding the TV in the bedroom, split it (just like the living room), with one end plugged into the 2nd Netgear router, and the other into the bedroom DVR?

In other words, can I have two modems in the house on the same Time Warner circuit? Would they have an IP conflict?

I still keep an XP laptop with Hyper Terminal for connecting to the console port on network devices since there is no Hyper Terminal on Win7 and later Win versions. Is there an alternative to Hyper Terminal in the later Windows? Is the USB-to-Com port working without a problem?

Also, how come some network devices have no console port? How can a higher-end network devices come without a console port?

Thank you for your help.

Hi, I am sick of our wireless around the office. There are so many blind spots.... Slow Wireless.

I decided to go all out and purchase a Cisco Aironet 3700 Series Access Point which set me back £650

TO be honest it seems to be just as bad as my £60 netgear access point.

I have set it up on 2.4g with it setup for range.

Is there a nack to this or can you recommend a repeater?

I have a customer that is wanting to extend their internet service from the office to their fire station.  The fie station is 400 feet from the office and is all metal building.  What is the best method of getting wifi out to the building (and also inside the building)?  

       Going under-ground with a cable is out of the question since we are crossing a main street and an all-slab parking lot.

I have a Gopro which I can connect to from my Surface Pro 3. The Gopro Hero4 Silver creates an AP to which my computer will connect and control it. But of course, when that happens, my WIFI internet is not working.

I then decide to try installing a USB Wireless Adapter to connect to the Internet while being connected to the Gopro in the first place. I dug out an old Wireless-G adapter from Linksys to try this. And it is working... sort of. That's why I am writing here to seek experts' advice as I cannot seem to find answers anywhere.

When I managed to get the two WIFIs turned on at the same time (built-in WIFI and the Wireless-G adapter), the Internet seems to be very spotty. It is definitely not as fast, and sometimes I feel it is still not simultaneous as the computer seems to be choosing one or the other to connect to the 'Internet', even though only 1 of it is having real internet. Ultimately, I wanted to use the Internet for Teamviewer connection, and while I could browse sometimes with the spotty Internet, the Teamviewer is not able to connect in it.

1) Is having two separate and simultaneous WIFI on 1 computer something possible that can work smoothly?
2) Is there some good practice I should do to tell the computer to use WIFI 1 for Internet, and WIFI 2 is something that does not have Internet so don't try it? Why does it seem that to the computer, WIFI must equal to Internet? I am a novice at networking, so I am just thinking of something like setting some …

Hi,
I have the following setup below and I am puzzled if there may be any performance/resource impact to the network if jumbo frames is setup as follows:

Host A ---mtu 1500----switch----mtu 1500-----router---mtu9000 with ospf----router----mtu 1500----switch---mtu 1500---host B

Host A IP:192.168.1.1/24
Host B IP: 192.168.2.1/24

a. If host A sends a file to host B; will there be any fragmentation/performance impact since only the router is setup for mtu support of 9K but host are sending with default mtu size of 1500 even though the file transfer works?


Any suggestion is appreciated.

Thanks.

I asked for a quote for one single mode fiber SFP LC connector - and at discount they want $700. Anyone know of a brand that's compatible with the 3750 switch that's more reasonable? Thanks.

I'm trying out the Unify AP  (UAP-LR)  products. I did my first install a month ago. Now I'm working to deploy two more for a separate company today. However, it appears the controller contains config data from the prior site. How do I setup an independent controller/AP situation or can I manage all my clients under one controller session?
